TIMING MECHANISM FOR ELECTRIC CIRCUITS.

Specification of Letters Patent.

Patented May 8,1906.

applied to motor electncally-driven vehicles, especially tram-cars, which is intended to check the car-driver by enabling the period durin current to be determined even after the journey is ended, and thus ascertaining whether the car-driver manages the working current economically or extravagantl One form of the invention 1s illustrated in the accompanying drawings, in which Figure 1 is a plan of the improved device, the current being interrupted; Fi 2, a simithe passage of t ecurrent; Fig. 3, the device for determining the number of times the current has been reversed; Fl 4, the choral arrangement of the contro er with t a controlling device on the front platform of the vehicle.

Ad 'oining the ordinary controller which serves for starting the motor a clock a, is arran ed, which is so connected with the contro or that when the current is interruptedthat is to say, when the car is traveling without current-it ceases to go, and, inversely, when the working current is switched on is set free to go a sun, and time when the journey is ended t e. exact period can be seen from the dial-plate durin which the meter was under the influence 0 current.

In the form of the invention as illustrated the shaft 5 of the controller isfurnished a cam 01, which is so'arranged that when he current is switched on it causes the two-armed lever h to swing around its pivot u. Opposipeftthe leiver h adlgveri1 1c is f h s a c an resse t e s against t e lever h. Al; the fro end th e lever k-is a spring 9, which ordinarily-that is to say, when the current is interruptcdlies against switched on by suitable rotation of the shaft tinue to go without hindrance.

'in device p, adjoinin which the motor is under the action of the .othe

pivoted on the b, the lever h, which is swung by the cam d around pivot it, forces the lever 1c so far back; Fig. 2, that the spring 9 leaves the balancewheel '5, and the clock a can be and conlh order that it may be possible to em by the movement of the lever k likewise gr winding up the clockwork, this lever is loosely arranged on the shaft 2; of the s rin -casing (not shown in the drawings) an is l u m, w 'ch engages in the teeth of the intermediate wheel a, firmly connected with the shaft 1; and prevented from turning backward by the pawl 0. Moreover, the reversthe controller -in r words, the shaft t ereof-is furnished with an enga g arm car a awl r, 3 which pus es the rate et -w eel g, and therewith the numbering-disk s, forward to the extent of one division when the lever p is operated for the purpose of reversing the direction of the current. The number of times when the operation just referred to is effected is indicate ticular figure appearing through the opent Vhat I claim, and desire to secure by Letters Patent, is-

An im roved check or indicator for determining t e time that the current is used in vehicles driven by electricity, consisting in the. combinationwith the controller, of a clock, and means for connecting the wheelwork of the clock with the controller in such a manner that when the current to the motor is switched ofi the clock is stopped, and when the motor is runmngthe w eelwork is set free and the clock started, said means com-' prising a cam fixed on the controller-shaft, a

two-armed lever arranged with one arm bearing a ainst said cars, a springressed singlearme lever bearing against t a other arm, and a spring on the single-armed lever arranged to normally bear on the balance wheel of the clock but capable of belng'removed therefrom to release said balancewheel, substantiall as described.
